First thing to keep in mind, make sure you have the IP for your server in the Remote Cron IP Address, that's what held me up for the most part, the "remote" part threw me off.

Next, I'm not sure how familiar you are with webhosting, but each location will be different, the web root location will be different for yours, than it is ours etc. With that in mind, an example may help, or it may not. Here is what I have:

/home/username/zweather/cronzweather yourwebsite.com

The "username" is the username for your website, not Joomla. Whatever you would use to FTP (if you're using the one setup by them not another you setup) or the username for logging in for changes etc.

The yourwebsite.com would be the address for your website.

The first part, the path to the file, is what you need to find out. If your host is using CPANEL this is very easy to do, just log into your cpanel (www.yoursite.com/cpanel) and scroll down until you see Home Directory /home/username. That's where I added the cron, which is actually under the webroot, it is not accessible to the web. Just the server itself. My web root, where Joomla is installed would be /home/username/public_html or the public_html could be a forward, such as /www which some hosts use too.

So assuming you put the cron folder just under your webroot, so that when you double click on public_html it goes to your files on the site, that would be how it's done. I hope I didn't confuse you, I tried to be as detailed as possible, and I am half asleep, working on only a couple hours of sleep If not, ask someone will help!
